Abstract: PURPOSE:To reduce the area of a cell and to make a decoding method easy by a method wherein a resistor region is formed between the part of a semiconductor substrate under an insulating film and other regions to which a write- inhibit voltage is not applied. CONSTITUTION:A resistor region 11 composed of an N-layer by a diffusion operation is formed between a channel part CH in a semiconductor substraet 1 under an insulating film 4 and a source region 3. The resistor region 11 is formed by using, e.g. phosphorus or arsenic as impurities in the case of the N-layer. When a write-inhibit voltage Vi is applied to a drain electrode D for a memory, a potential distribution from a drain region 2 to the source region 3 does not exist in a part where the voltage is dropped to O V under the insulating film 4. As a result, an electric charge is not trapped inside the insulating film 4, strictly speaking, inside a nitride film 7, and an aim not to write the electric charge can be achieved. Consequently, it is not required to from a transistor for write-inhibit, the area of a memory cell can be reduced, and the number of interconnections required in a write operation can be reduced.
